Whether you're building a high-horsepower naturally aspirated S54 or stepping into serious boost, the Fuel Injector Clinic IS801-1200H Fuel Injector Set delivers the fuel volume and precision required to support your performance goals. This complete set of six 1200cc saturated (high impedance) ball and seat injectors utilizes the latest injector technology to provide outstanding fuel control, excellent linearity, and exceptional short pulse width repeatability for smooth idle quality, crisp throttle response, and consistent drivability. This injector set is a Plug and Play fit to the factory OEM wiring harness, making installation simple with no wiring modifications required.
Previously sold as IS801-1100H, the IS801-1200H benefits from Fuel Injector Clinic's proprietary Data Match Technology, where every injector is individually flow tested, dynamically matched, and serial numbered to deliver unmatched consistency. Each injector set includes a comprehensive Data Match Sheet with individual flow and latency values for accurate ECU calibration. Flow testing is performed at 43.5 PSI (3 Bar) using CF-16B calibration fluid at 90 degrees Fahrenheit. Every injector includes the required O-rings for the factory application and is backed by Fuel Injector Clinic's Lifetime Warranty against defects in original manufacture.
